1. A turbine wheel comprising:
a hub that comprises a rotational axis, a backdisk and a nose, wherein the rotational axis defines an axial coordinate (z) in a cylindrical coordinate system that comprises a radial coordinate (r) and an azimuthal coordinate (Θ) in a direction of intended rotation about the rotational axis; and
blades that extend outwardly from the hub, wherein each of the blades comprises a leading edge and a trailing edge, wherein the leading edge comprises a lower axial point defined by a first theta angle and an upper axial point defined by a second theta angle, wherein the first theta angle is greater than the second theta angle with respect to the direction of intended rotation of the turbine wheel.
